Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15608, here are decompositions:
- 7 + 15601 = 15608
- 67 + 15541 = 15608
- 97 + 15511 = 15608
- 157 + 15451 = 15608
- 181 + 15427 = 15608
- 277 + 15331 = 15608
- 331 + 15277 = 15608
- 337 + 15271 = 15608
Showing the first eight; more decompositions exist.
